Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A projector comprising: a projecting section projecting a whole image including an individual image and having a function of adjusting the size of the whole image, the whole image being configured to be projected on a screen; an image taking section taking an image of the screen; an updating section detecting a position change instruction based on the image taken by the image taking section, and updating position data which shows a position of the individual image according to the position change instruction; and a control section performing control so as to make the projecting section adjust the size of the projected whole image according to the position data in a state in which the whole image includes a whole of the individual image, wherein the control section determines whether or not the individual image moves out of the whole image according to the position data and enlarges the size of the whole image when the individual image moves out of the whole image.
A projector displays a whole image, including an individual image, onto a screen. The projector captures an image of the screen and detects position changes of the individual image based on that captured image. It then updates the position data for the individual image. The projector adjusts the size of the displayed whole image based on the individual image's position data, ensuring the individual image always remains fully within the whole image. If the individual image moves outside the boundaries of the whole image according to the position data, the projector automatically enlarges the whole image.
2. The projector according to claim 1 , wherein the image taking section takes an image of a projection target region on which the whole image is projected by the projecting section and generates taken-image information, and the control section performs control based on the taken-image information.
A projector system is designed to project images onto a target surface while dynamically adjusting projection parameters to optimize image quality. The system includes a projection unit that emits light to display an image on a target surface, such as a wall or screen. An image capture unit is positioned to capture an image of the projection target region, generating captured image data. A control unit processes this data to analyze the projection environment, including factors like surface geometry, ambient lighting, and alignment. Based on this analysis, the control unit adjusts projection parameters, such as focus, brightness, or distortion correction, to enhance image clarity and accuracy. The system may also detect obstacles or irregularities in the projection area and compensate for them in real time. This adaptive approach ensures consistent image quality across varying projection conditions, improving user experience in dynamic environments. The invention addresses challenges in maintaining optimal projection quality when environmental factors or surface characteristics change, providing a self-correcting solution for accurate and high-quality image display.
3. The projector according to claim 2 , wherein the control section performs control based on instruction information showing an instruction content included in the taken-image information.
The projector from the previous description operates using instruction information found within the captured image data. This instruction information contains commands dictating projector behavior. The projector analyzes the image data to interpret these commands and then adjusts its projection parameters accordingly. This enables control based on visual cues or signals present in the projected environment.
4. The projector according to claim 3 , wherein the instruction information is information showing an instruction light generated as a result of an instructing section emitting light or reflecting light, and when the instruction light moves multiple times in different directions within a predetermined time and a position to which the instruction light is projected is the position of the individual image, the control section controls the projecting section so as to erase the individual image.
The projector described previously uses light as an instruction. If a user shines light in different directions multiple times within a certain timeframe and the final light position is on the individual image, the projector will erase the individual image. The light acts as a trigger and target mechanism for removing unwanted elements.
5. The projector according to claim 4 , wherein the individual image is an image showing the trajectory of the instruction light, and when the instruction light moves multiple times in different directions within a predetermined time and a position to which the instruction light is projected is the position of the image showing the trajectory, the control section controls the projecting section so as to erase the image showing the trajectory.
Building on the projector with light-based control described previously, if the individual image is actually a trajectory or path created by the instruction light, the same erase functionality applies. Rapid, multi-directional light movement ending on the light-drawn path will trigger the projector to erase that drawn path or trajectory image. This creates an interactive drawing and erasing function.
6. The projector according to claim 1 , comprising: a storing section storing the position data showing the positions and sizes of the individual image and the whole image; wherein the updating section updates the position data based on taken-image information generated by the image taking section, and the control section performs control based on the position data.
The projector described previously includes memory that stores position and size data for both the individual and whole images. The image taking section provides image data for updating the position information of the individual image. The projector controls projection based on this stored position data. This data management allows for precise adjustments and tracking of image elements.
7. The projector according to claim 6 , comprising: a transmitting section, wherein when an instruction corresponds to a distribution instruction to distribute the individual image, the control section performs, based on the position data, control so as to make the transmitting section transmit image data of the individual image to a device to which the individual image is distributed.
The projector described previously has the capability to transmit the individual image to another device. If the projector receives an instruction to distribute the individual image, it utilizes the stored position data to properly extract and transmit the image data. This feature allows for easy sharing and collaboration with other devices.
8. The projector according to claim 1 , wherein the control section performs control to adjust the size of the whole image by enlarging and moving an image showing the whole image in a displayable region of an optical modulator included in the projecting section.
The projector described previously adjusts the size of the whole image by manipulating a displayable region inside the optical modulator. The projector moves and expands the region which contains the whole image within the modulator. This method of image scaling allows the projector to modify the image size directly at the light source, creating a dynamic and adaptable display output.
9. A control method performed by a projector, comprising: projecting a whole image including an individual image, the whole image being configured to be projected on a screen, the step being performed by a projecting section of the projector; taking an image of the screen, the step being performed by an image taking section of the projector; detecting a position change instruction based on the image taken by the image taking step, and updating position data which shows a position of the individual image according to the position change instruction, the step being performed by an updating section of the projector; and adjusting the size of the projected whole image according to the position data in a state in which the whole image includes a whole of the individual image, the step being performed by a control section of the projector, and determining whether or not the individual image moves out of the whole image according to the position data and enlarging the size of the whole image when the individual image moves out of the whole image, the step being performed by the control section of the projector.
A projector control method involves projecting a whole image (containing an individual image) onto a screen. An image of the screen is captured. Based on the captured image, position change commands for the individual image are identified. The individual image's position data is updated accordingly. The whole image's size is adjusted to ensure the individual image remains fully visible inside it. If the individual image moves outside the boundaries of the whole image, the whole image is automatically enlarged.
10. The projector according to claim 1 , wherein: the control section performs control based on instruction information, the instruction information being information showing an instruction light generated as a result of an instructing section emitting light or reflecting light, when the instruction light moves multiple times in different directions within a predetermined time and a position to which the instruction light is projected is the position of the individual image, the control section controls the projecting section so as to flash the individual image, and when the instruction light moves further multiple times within a predetermined time, the control section controls the projecting section so as to erase the flashed individual image.
The projector described previously reacts to light signals used as commands. If instruction light moves repeatedly in various directions within a set period and ends at the individual image’s position, the projector causes the individual image to flash. If the light is moved in this way additional times, then the projector will erase the flashing image. This provides a mechanism for selecting and then removing specific displayed items using directed light gestures.
